EG2124 from EG Micro, in a QFN-24-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 LIN1 input Low-side logic input for channel 1 that controls LO1 (datasheet lists this pin as active-low, which conflicts with the active-high truth table; logic high threshold is 2.5 V min, low threshold 1.0 V max, with an internal 240 kΩ pull-down).
2 LIN2 input Low-side logic input for channel 2 that controls LO2 (datasheet lists this pin as active-low, which conflicts with the active-high truth table; logic high threshold is 2.5 V min, low threshold 1.0 V max, with an internal 240 kΩ pull-down).
3 LIN3 input Low-side logic input for channel 3 that controls LO3 (datasheet lists this pin as active-low, which conflicts with the active-high truth table; logic high threshold is 2.5 V min, low threshold 1.0 V max, with an internal 240 kΩ pull-down).
4 VCC power_in Low-side and analog supply, operating 5 V to 20 V (absolute maximum -0.3 V to 25 V).
5 NC unconnected No connection (listed as NC in the QFN24 pin table).
6 GND power_in Analog ground reference for the device.
7 NC unconnected No connection (listed as NC in the QFN24 pin table).
8 NC unconnected No connection (listed as NC in the QFN24 pin table).
9 LO1 output Low-side gate drive output for power MOSFET channel 1, with absolute maximum range -0.3 V to VCC+0.3 V and an internal 70 kΩ pull-down.
10 LO2 output Low-side gate drive output for power MOSFET channel 2, with absolute maximum range -0.3 V to VCC+0.3 V and an internal 70 kΩ pull-down.
11 LO3 output Low-side gate drive output for power MOSFET channel 3, with absolute maximum range -0.3 V to VCC+0.3 V and an internal 70 kΩ pull-down.
12 VS1 power_in Floating high-side return for channel 1, with absolute maximum range VB-25 V to VB+0.3 V.
13 HO1 output High-side gate drive output for channel 1, with absolute maximum range VS-0.3 V to VB+0.3 V and an internal 70 kΩ pull-down.
14 VB1 power_in Floating high-side bootstrap supply for channel 1, with absolute maximum rating of 280 V.
15 VS2 power_in Floating high-side return for channel 2, with absolute maximum range VB-25 V to VB+0.3 V.
16 HO2 output High-side gate drive output for channel 2, with absolute maximum range VS-0.3 V to VB+0.3 V and an internal 70 kΩ pull-down.
17 VB2 power_in Floating high-side bootstrap supply for channel 2, with absolute maximum rating of 280 V.
18 VS3 power_in Floating high-side return for channel 3, with absolute maximum range VB-25 V to VB+0.3 V.
19 HO3 output High-side gate drive output for channel 3, with absolute maximum range VS-0.3 V to VB+0.3 V and an internal 70 kΩ pull-down.
20 VB3 power_in Floating high-side bootstrap supply for channel 3, with absolute maximum rating of 280 V.
21 NC unconnected No connection (listed as NC in the QFN24 pin table).
22 HIN1 input High-side logic input for channel 1 that controls HO1, active high; logic high threshold is 2.5 V min, low threshold 1.0 V max, with an internal 240 kΩ pull-down.
23 HIN2 input High-side logic input for channel 2 that controls HO2, active high; logic high threshold is 2.5 V min, low threshold 1.0 V max, with an internal 240 kΩ pull-down.
24 HIN3 input High-side logic input for channel 3 that controls HO3, active high; logic high threshold is 2.5 V min, low threshold 1.0 V max, with an internal 240 kΩ pull-down.
